GEORGE S. GREENE, OF ST. CLAIRSVILLE, OHIO.

MINE-CAR BUMPER.

To (4U iii/mm it may concern Be it known that I, Gnonen Fl. Guzman, a citizen of the United States, residing at St. Clairsville, in the county of Belmont and State of Ohio, have invented certain new and useful li'nprovements in Mine-Car Bumpers, of which the following is a specitieation.

This invention relates to mine ears, and particularly to the bumpers and draw-bars thereof.

The object of the invention is to provide such cars with an improved form of bumper, which will avoid the mutilation or breakage of the coupling link .or of the parts of the draw head, and which can be repaired or renewed at a low cost and in a convenient manner.

The ordinary type of draw-bar is objectionable and gives considerable trouble by reason of breakage of the draw-bar or link when the cars come together with a shock.

By means of my improvement the draw head is protected, and a space is provided so that the link will not receive the impact of cars humping together.

The invention can be easily applied to the ordinary type of mine car without particular modification thereof. It comprises a new form and construction of the bumper head as will more fully appear from the following description and the accompanying drawings.

In the drawings, Figure 1 is a plan view of the bumper. Fig. 2 is a side elevation. Fig. 3 is a section on the line 3-3 of Fig. 2.

.teferring specifically to the drawings, (3 indicates the main or middle sill of the car which :is extended beyond the end thereof as usual, and 7 is the metal draw bar or plate which extends throughout the length of the car, and is suitably fastened to the middle beam or floor, and terminates short of the end thereof, as shown.

The end of the sill is provided with a metal binder 8 which is bent or fitted around the sides and front of the sill, as shown in Fig. 1 and this binder is fastened to the sill by transverse bolts 9 extending through the sill. This protects the end of the sill and forms the bumper which contacts with the similar bumper of an adjacent car when the cars come together.

The upper surface of the sill, at the end thereof, is provided with a top plate 10, and

the lower surface, is provided with a but tom plate 11, these plates being made of metal, and being the same shape, in plan, as the end of the sill, and they are set in recesses made in the sill so that they are llnsh with the top and bottom surfaces of the sill respectively and with the edges of the binder 8. They serve to support the binder and to strengthen the sill, and the upper plate forms a surface on which the link rests when the cars are coupled. These top and bottom plates are secured to the sill by countersunk bolts 12.

An arched draw plate 13 is mounted on top of the sill, the edges of said plate being angular and bent or set down to form flanges 14 at opposite sides, these flanges resting on top of the sill where they are secured by vertical bolts 15 extending tlnrough the sill. The plate forms an arched passage or recess 10 thereunder, of sullicient height to permit a link to pass back into the recess and under the plate, so that the link will not be ammed against the draw head, as in the old construction. The front end of the draw plate 113 does not extend out as far as the end of the sill t3, and consequently cannot receive the bumpii'ig impact of cars. Said end is provided with a hole 17, in line with the hole 18 in the sill, to receive the ordinary coupling pin. The rear end of the arched plate 11-} is bent down as indicated at 19 and'is attached by bolts 20 to the d aw plate 7 and the sill (5.

The pulling strain on the car is thus mainly communicated through the plate 13 to the draw-bar 7 and the middle sill.

When the coupling link enters the space between the front end of the draw plate 1?, and the plate 10 it may pass or work back into the recess 16, and so be relieved of any impact incident to operation of the cars. In the event of breakage of any of the metal parts they can be easily replaced. This is particularly adwmtageous with respect to the draw plate 13, which some times breaks. To replace it, it only necessary to take all the old plate by removing the bolts 15 and 20, and put a new one on, and this can be done without renewing the other parts of the lJllIl'lPOl' head, and is superior to the old form in which the draw plate was integral with the bumper or was welded to the draiw bar 7, requiring either a new bumper head or the welding of a new draw plate to the end of tl1e,d1'a -b ar,as ellies. putting the car out of use for a considerable period of time. 7

I claim:

The combination with a sill provided at its end with a top plate, and a draw-bar mounte d o topptthe sill, of a draw plate having a hole for the coupling pin, said draw plate being arched transversely to the 10 sill and bolted at its side edges to the sill,

Copies of this patent may be obtainedfor fivedeents and bolted atits rear end to the draw-bar, whereby. the draw plate may be removed Without removal. of. the top plate or the draw-bar.

In testimony whereof, I afiiX my signature 15 each, by. addressing the Commissioner of Patents,
